摘　　要：目的:研究辅助生殖中体外受精-胚胎移植(in vitro fertilization and embryo transfer,IVF-ET)技术对早期胎盘滋养层细胞黏着斑激酶(focal adhension kinase,FAK)信号通路基因表达的影响,探讨IVF-ET技术对早期胎盘发育和功能的影响。方法:收集IVF-ET来源的于7～8周经超声引导下减胎获得的胎盘绒毛组织作为研究组,对照组采用自然妊娠双胎7～8周人工流产术中获得的胎盘绒毛组织。利用美国Affymetrix HG-U133 Plus 2. 0基因芯片对两组胎盘绒毛组织进行芯片杂交分析,实时定量聚合酶链反应(real-time quantitative polymerase chain reaction,qRT-PCR)验证其中8个差异表达基因,选取差异表达基因进行无监督聚类分析和生物信息学分析。结果:获得4例IVF-ET减胎绒毛组织和4例自然妊娠人工流产绒毛组织进行基因芯片检测。与自然妊娠组相比,IVF-ET组FAK信号通路中有32个基因差异表达,差异表达倍数≥2,其中12个基因上调,20个基因下调。经qRT-PCR验证,IVF-ET与自然妊娠早期胎盘绒毛中的8个FAK信号通路基因表达确实存在差异,与基因芯片检测结果一致。FAK信号通路基因定位显示,IVF-ET来源胎盘绒毛组织FAK信号通路上游基因表达受到影响,胎盘滋养层细胞通过基因表达代偿维持FAK信号通路功能基本正常。结论:IVF-ET来源和自然妊娠来源的早期胎盘FAK信号通路存在基因表达差异,差异表达基因涉及多种FAK信号通路关键功能,影响IVF-ET胎盘绒毛早期发育和功能,同时胎盘滋养层细胞通过改变相关基因表达来代偿IVF-ET技术本身的干扰,以维持FAK信号通路正常功能,满足胎盘绒毛和胎儿发育需要。Objective: To study the effects of in vitro fertilization-embryo transfer (IVF-ET) technique on gene expression of focal adhension kinase (FAK) signaling pathway in early placental trophoblast cells, and to explore the effects of IVF-ET technology on the development and function of early placenta. Methods: We collected 7-8 weeks of gestation placenta tissue as a study group by ultrasound guided reduction of fetal from double embryo transfer under IVF-ET technology. In the control group, placenta tissues were obtained from the spontaneous abortion of natural pregnancy twin 7-8 weeks. Microarray hybridization analysis was performed on the placenta tissue of the two groups using the Affymetrix HG-U133 Plus 2.0 gene chip. Eight differentially expressed genes were identified by real-time quantitative polyme-rase chain reaction (qRT-PCR), and unsupervised clustering analysis and functional bioinformatics analy-sis were performed for the differentially expressed genes. Results: Twenty-eight cases of IVF-ET reduced fetal villi and 8 cases of spontaneous abortion villi were collected. A total of 8 placental villi were detected by the gene chip. Compared with the natural pregnancy control group, 32 differentially expressed genes in the placental FAK signaling pathway were expressed in IVF-ET. The differential expression was greater than or equal to 2 times, of which 12 genes were up-regulated and 20 were down-regulated. The qRT-PCR showed that the expression of the 8 genes in FAK signaling pathways of IVF-ET was significantly different from that in the placenta of natural pregnancy, which was consistent with the result of the gene chip detection. The FAK signal pathway gene localization showed that the FAK gene was mainly located in the upstream of the signal pathway in the placenta of IVF-ET. The placental trophoblast cells maintained the FAK signaling pathway function through gene expression compensation. Conclusion: There are gene expression differences in the FAK signaling pathway between the IVF-ET derived early place
